BACKGROUND: The effects of elexacaftor/tezacaftor/ivacaftor (ETI) on respiratory outcomes for people with CF (pwCF) were demonstrated by several clinical trials, mainly based on simple spirometry. However, gains in lung function may vary greatly between patients, but predictors of FEV1 change after treatment are still missing. RESEARCH QUESTION: Which ventilatory parameters are involved in the heterogeneity of FEV1 change after 12-month ETI treatment in pwCF with advanced lung disease? STUDY DESIGN: AND METHODS: This was a multicenter, observational, prospective cohort study at two major CF centers in Italy...

BACKGROUND: Airway obstruction is defined by spirometry as a low forced expiratory volume in 1 s (FEV1 ) to forced vital capacity (FVC) ratio. This impaired ratio may originate from a low FEV1 (classic) or a normal FEV1 in combination with a large FVC (dysanaptic). The clinical implications of dysanaptic obstruction during childhood and adolescence in the general population remain unclear. AIMS: To investigate the association between airway obstruction with a low or normal FEV1 in childhood and adolescence, and asthma, wheezing and bronchial hyperresponsiveness (BHR)...

Secretion retention, atelectasis, and reduced lung compliance occur when endotracheal or tracheostomised patients cough ineffectively. There is a possibility of infection if the collapsed regions of the lungs are not reinflated. Therefore, to improve clinical outcomes, such as diaphragm mobility and thickness, lung volume, and thickness of the abdominal muscles, and decrease the length of hospitalizations, mechanical and manual techniques, such as balloon blowing exercises and incentive spirometer, are required...

RATIONALE: Individuals with COPD have airflow obstruction and maldistribution of ventilation. For those living at high altitude, any gas exchange abnormality is compounded by reduced partial pressures of inspired oxygen. OBJECTIVES: Does residence at higher-altitude exposure affect COPD outcomes, including lung function, imaging characteristics, symptoms, health status, functional exercise capacity, exacerbations, or mortality? METHODS: From the SPIROMICS cohort, we identified individuals with COPD living below 1,000 ft (305 m) elevation (n= 1,367) versus above 4,000 ft (1,219 m) elevation (n= 288)...

BACKGROUND: Patient engagement attrition in mobile health (mHealth) remote patient monitoring (RPM) programs decreases program benefits. Systemic disparities lead to inequities in RPM adoption and use. There is an urgent need to understand patients' experiences with RPM in the real world, especially for patients who have stopped using the programs, as addressing issues faced by patients can increase the value of mHealth for patients and subsequently decrease attrition. OBJECTIVE: This study sought to understand patient engagement and experiences in an RPM mHealth intervention in lung transplant recipients...

INTRODUCTION: Studies suggest peripheral airway abnormalities in Pulmonary Arterial Hypertension (PAH). Impulse Oscillometry (IOS) is a noninvasive and sensitive technique for assessing the small airways. It evaluates the impedance of the respiratory system ‒ Resistance (R) and reactance (X) ‒ to a pulse of sound waves sent to the lungs, in a range of frequencies (5‒20 Hz). METHOD: Resistance variables: R5, R20, R5-R20 and reactance variables: AX (reactance area) and Fres (resonance frequency)...
